Reverse proxy with a subdirectory to a server at top level January 07, 2011 01:37PM |

I've been working with NGINX for a little while now but am having trouble solving a particular issue.
I have a set of machines that each run a third-party reporting server. This third-party system puts its web server at the top level of the domain. I can hit it by going to https://reportserver_ip/ only. I can change the port but can not put it in a subdirectory.
I want to use NGINX to reverse proxy to these servers. My goal is to have one domain hit the correct reporting servers based on a subdirectory. Example:
https://mypublicdomain/report1
https://mypublicdomain/report2
https://mypublicdomain/report3
Each would end up reverse proxying to its respective report server.
However, this third-party report server has a number of links that are non-relative.
For example an img with src="\images\..." or a link to javascript at href="\javascripts\..."
Since those links don't have the respective "report1" or "report2" in the url, NGINX doesn't know where to send them.
I can get this working if I reverse proxy to the report servers using different subdomains (report1.mypublicdomain) or different ports (mypublicdomain:XX1) but for different reasons I really need them to all be on the same domain and port.
Is there a way to do this? Can I set it up somehow so that even though the report servers have those non-relative links they will end up proxying to the right place?
If I had control over the third-party reporting tool, I'd just add a base tag to the html head and it would work, but I don't have the ability to do that.
Thanks for help or ideas anyone can provide.

Well, we've been working on this and thought we had come up with a solution.
The idea was to use HttpSubsModule and HttpSubModule.
(http://wiki.nginx.org/HttpSubsModule and http://wiki.nginx.org/HttpSubModule)
I figured I could use HttpSubModule to add a <base> tag to the <head> element which specified the url and subdirectory AND to use HttpSubsModule to get rid of all instances of leading forward slashes in references.
Unfortunately, the third-party report servers use compressed http using gz. And from the forums it looks like HttpSub and HttpSubs don't work with gzipped responses. I haven't seen any workarounds for this online.
So, is there a different way to solve the initial issue? Or, alternatively, is there a way to use the HttpSubsModule with a compressed http response?
Thanks again for any help,
Jeff
